Hi Trond,

Is this patch going to be dropped and re-submitted?   It has obvious
typos that have been causing reported build failures[1] in linux-next
for a week now.   In addition to that, it has several whitespace errors
(long lines, no space after comma, etc.) that I bet checkpatch.pl
would have found, if it was used.

Commit 4494c750240bab1bb83bd8f4d5a268663c37c9b3 in next-20120130.

Thanks,
Paul.
